When comparing web browsing and downloading speeds of Vista against older versions of Windows, you might find there is a noticable speed difference. Sites just seem to open slower in Vista than in Windows XP and Server 2003.
Never fear, there is hidden secrets that might help with this problem…
Follow these steps below and see the difference.
Opening IE 7, go to the “Tools” menu and select “Internet Options” (you will find this in the Control Panel as well). Go to the Advance Tab and scroll right down to the Security section. Tick the SSL 2.0 box and untick the TLS (Transport Layer Security) box. Click Apply and then OK.
TCP Autotuning is enabled by default on Windows Vista. This could result in some web servers to improperly respond to web site requests, making the sites seem slower.
Logged in with Administrative rights, do the following:
Open up Command Prompt (Start Button, in the search box type “cmd”, once it shown, enter on it).
At Command Prompt, type the following command and press enter. The screen should look like below:
netsh interface tcp set global autotuninglevel= disabled
This command will disable the TCP autotuning feature. Close the Command Prompt window and restart your windows for the settings to take effect.
To restore the settings to the defaults again, open up the Command Prompt again as above, but use this command:
netsh interface tcp set global autotuninglevel= normal
Again restart the windows for the settings to take effect.
Hope this helped you and it helped me?!
